Solving vibration problems in a two-phase flowline

Two-phase flow refers to the interactive flow of two distinct phases with common interfaces in a piping system, with each phase representing a mass or volume of matter. The two phases can exist as combinations of solid, gas, and/or liquid phases. Although multiphase flow involving three phases can also exist, most multiphase engineering applications are two-phase flow.

Two-phase flow exists in many process piping and power piping components. The flowing fluid is a source of energy that can induce small-amplitude subcritical oscillations and large-amplitude dynamic instabilities. In fact, many practical system components have experienced excessive flow-induced vibrations. To prevent unacceptable flow-induced vibration, Users must understand excitation mechanisms, develop analytical and experimental techniques, and provide reliable design guidelines.

In this video collection presented by Dynaflow research group, the basics of vibration because of two-phase flow, is clarified by the presenter. Hope, most of you will get a good insight to solve the two-phase vibration problems. If you wish to add something more please write in the comments section.
